So in this repo we have:
-
Vagrant configured to deploy kubernetes cluster (2 nodes) automatically on Mac via Parallels Desktop provider.
-
Terraform to do the same on Yandex Cloud.
-
Both run ansible playbooks upon finish.
-
After Ansible is run we have a cluster which has 2 nodes - master and slave
-
We use 3 helm charts:
- local-volume-provisioner - for automatic pv provisioning
- postgresql - db
- nginx-ingress - for access over http
-
We also must install secret with docker credentials and a secret with SSL certificates.
-
The chart for application is located in kubernetes/blogd directory
To run django_todo I modified my exisitng web-site. All the changed performed are available here: mtuktarov/mtuktarov.ru#7
Dockerfile is also located in this repo: https://github.com/mtuktarov/mtuktarov.ru/blob/django-todo/Dockerfile Note: you must use 'django-todo' branch
- Look at
kubernetes/README.mdfor deploying examples
- I do not store any web-site files in container I run
git clone $branchon a startup - uwsgi container is sharing pod with nginx container
- for developing purposes you can run container with envvar
TEST_SERVER=trueand it will launch native django web server - uwsgi outputs in the unix socket by default, uwsgi args can be changed using env var
